AF performance

  • AF was moderately fast
  • AF was problematic specially when focusing as of F5.6 or in the corners but relatively good at F2 around the centre
  • AF for burst was ok in general
  • Let’s hope TTArtisan will further improve the AF via firmware upgrade

Performances AF

  • L’AF est moyennent rapide,
  • L’Af était problématique dans certains cas: à F5.6 ou avec un collimateur dans les coins
  • Pour de la rafale sur sujets en mouvements l’optique perd le point pour les sujets rapides quand ils sont proches (<2m)
  • Esperons que TTArtisan améliore l’AF via des mises à jour
  • Dans de rare cas j’ai eu un AF bloqué et j’ai du repasser en MF puis directement de retour en Af pour restaurer la mise au point

4.3 Background Blur & Bokeh Balls / Flous d’arrière plan et Ronds de Bokeh

  • The Samyang 45mm F1.8 AF have a bit better bokeh balls (more circular) and background blur thanks to its higher number of aperture blades and better aperture

  • The TTArtisan has one of the longest min focusing distance and the most nervous background
  • Le Samyang 45mm F1.8 AF a des ronds de Bokeh légèrement meilleurs grâce à son nombre plus élevés de lames de diaphragme et leur plus grande ouverture
  • Le Sony a un avantage sur la taille des ronds de bokeh à ouverture identique car sa distance min de mise au point est beaucoup plus courte (tout comme le Sigma)
  • Le Viltrox est très bon mais moins que ses concurrents

Autofocus

AF of the Sony is better than on the Samyang , the less good being the Sigma/Viltrox. The Sony are the only one compatible with the 30fps of the A1. The TTArtisan is the least good one

L’AF du Sony est meilleur que celui du Samyang , les Sigma / Viltrox sont un peu moins bons. Les Sony sont les seuls compatible avec les 30 images/sec du Sony A1. Le TTArtisan est le moins bon

Video :

Ergonomics for video are best on the Sony 40/50mm F2.5 G, but the other lenses opening at F1.2/F1.8/F2 provide more creative possibilities thanks to their better aperture

L’ergonomie en vidéo est meilleure sur les Sony 40/50mm F2.5 G , mais les autres optiques ouvrant à F1.2/F1.8 /F2 offrent plus de possibilité créatives

Conclusion

Overall the Sony is the best lens in term of Size, sharpness, resistance to flare, ergonomics, build quality , the only area were other score better is for portraits with better bokeh balls/background blur when they offer a F1.2/F1.8 aperture and/or a longer focal length

The Viltrox is offering 80% of Sony performances for 25% of the price of The Sony

The TTArtisan is at same price of the Viltrox and same form factor but is significantly less good

Globalement le Sony est le meilleur en terme de taille, piqué, resistance au flare, ergonomie, qualité de construction. Le seuls point où les autres sont meilleurs est en portrait avec une meilleure forme des ronds de Bokeh, plus de flou d’arrière plan

Le Viltrox lui offre 80% des performances du Sony pour 25% de son prix !

Le TTArtisan est très similaire en prix et taille que le Viltrox mais nettement moins bon
